njkwebviewprogress's Introduction

NJKWebViewProgress

NJKWebViewProgress is a progress interface library for UIWebView. Currently, UIWebView doesn't have official progress interface. You can implement progress bar for your in-app browser using this module.

NJKWebViewProgress doesn't use CocoaTouch's private methods. It's AppStore safe.

Used in Production

Requirements

iOS 4.3 or later
ARC

Usage

Instance NJKWebViewProgress and set UIWebViewDelegate. If you set webViewProxyDelegate, NJKWebViewProgress should perform as a proxy object.

_progressProxy = [[NJKWebViewProgress alloc] init]; // instance variable
webView.delegate = _progressProxy;
_progressProxy.webViewProxyDelegate = self;
_progressProxy.progressDelegate = self;

When UIWebView start loading, NJKWebViewProgress call delegate method and block with progress.

-(void)webViewProgress:(NJKWebViewProgress *)webViewProgress updateProgress:(float)progress
{
    [progressView setProgress:progress animated:NO];
}

progressProxy.progressBlock = ^(float progress) {
    [progressView setProgress:progress animated:NO];
};

You can determine the current state of the document by comparing the progress value to one of the provided constants:

-(void)webViewProgress:(NJKWebViewProgress *)webViewProgress updateProgress:(float)progress
{
    if (progress == NJKInteractiveProgressValue) {
        // The web view has finished parsing the document,
        // but is still loading sub-resources
    }
}

This repository contains iOS 7 Safari style bar NJKWebViewProgressView. You can choose NJKWebViewProgressView, UIProgressView or your custom bar.
